A Cryptanalysis of the High-Bandwidth Digital Content Protection System
White Paper HDCP is a proposed identity-based cryptosystem for use over the Digital Visual Interface bus, a consumer video bus used to connect personal computers and digital display devices. This paper describes a weakness in the High Bandwidth Digital Content... [08 Jul 2008]
Architectural Extensions for Elliptic Curve Cryptography Over GF(2m)
White Paper This paper describes data path extensions for general-purpose microprocessors to accelerate the emerging public-key cryptosystem Elliptic Curve Cryptography (ECC). ECC is computationally more efficient than the popular RSA cryptosystem and, thus... [02 Aug 2005]
Universal Re-Encryption for Mixnets
White Paper This paper proposes a new type of public-key cryptosystem that permits universal re-encryption of ciphertexts. This paper introduces the term universal encryption to mean re-encryption without knowledge of the public key under which a ciphertext... [17 Jun 2004]
A Cryptographic Checksum for Integrity Protection
White Paper The technique is based on the use of repeated encryption using an RSA cryptosystem as a pseudo-random number generator (PRNG), the use of a user specified key as a seed for the PRNG, and reduction in a pseudo-random modulus as a means for mixing... [08 Mar 2004]
Differential Power Analysis
White Paper Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. [08 Mar 2004]
NTRU: A Ring Based Public Key Cryptosystem
White Paper We describe NTRU, a new public key cryptosystem. The security of the NTRU cryptosystem comes from the interaction of the polynomial mixing system with the independence of reduction modulo two relatively prime integers p and q. [24 Feb 2004]
Twenty Years of Attacks on the RSA Cryptosystem
White Paper Two decades of research led to a number fascinating attacks on RSA. It surveys several attacks and classifies them into four categories: elementary attacks, attacks on low private exponent, attacks on low public exponent, and attacks on the... [24 Feb 2004]
Reaction Attacks Against Several Public-Key Cryptosystems
White Paper We present attacks against the McEliece Public-Key Cryptosystem, the Atjai-Dwork Public-Key Cryptosystem, and variants of those systems. Most of these systems base their security on the apparent intractability of one or more problems. [24 Feb 2004]
Are 'Strong' Primes Needed for RSA?
White Paper In this white paper we review the arguements in favor of so-called "strong primes" in the RSA public key cryptosystem. There are two types of such arguments: those that say that strong primes are needed to protect against factoring attacks, and... [24 Feb 2004]
A Method for Fast Revocation of Public Key Certificates and Security Capabilities
White Paper The use of a SEM in conjunction with a simple threshold variant of the RSA cryptosystem (mediated RSA) offers a number of practical advantages over current revocation techniques. The article asserts the concept of an on-line semi-trusted mediator... [24 Feb 2004]
Why Cryptosystems Fail
White Paper It turns out that the threat model commonly used by cryptosystem designers was wrong: most frauds were not caused by cryptanalysis or other technical attacks, but by implementation errors and management failures. [24 Feb 2004]
Multi-Grade Cryptography
White Paper We call it multi-grade cryptography because it makes a single cryptosystem appear to present multiple levels of security. The recent development of powerful cryptographic techniques has caused a number of public policy issues to become significant. [24 Feb 2004]
The NHS as a Proving Ground for Cryptosystems
White Paper This paper gives a detailed overview of the features and challenges the NHS environment presents to uses of cryptography, to qualify impressions of our cryptosystem and to guide future efforts to develop it. [24 Feb 2004]
Securit-e-Vault Technical White Paper
White Paper The core technology within Securit-e-Vault is the SITT (Secure Information Transport Technology) Cryptosystem. Securit-e-Vault is a full-featured file and message transport, management and storage solution, whose modular architecture creates a... [24 Feb 2004]
IBM technology blocks active attacks
News Known as the 'Cramer-Shoup' cryptosystem, it is a coding system that secures information sent over public networks. IBM Research has unveiled a cryptography system which it claims is the best yet at preventing the most dangerous hacker invasions... [25 Aug 1998]
